mitchm2009,
Same surgery here at Mayo on April 15th, 2020. 3rd incision along the right entire ribcage. That bugger still gives me significant pain. 5 mg Oxycodone as needed. I also do very light stretching while still in bed in the morning but am extremely careful. The pain meds cause me constipation ( no ulcerative colitis here ). I'm a retired Certified Dietary Mgr. so I was pretty much in charge of my own diet ( the Registered Dietician at the cancer center drove me nuts). For constipation I drink 8 oz ( 4 oz at a time x 2 ) daily. This may not be an option for you with your indigestion. As you probably know..... either cooked or raw veggies help, applesauce, bran cereal ( I prefer mini wheats, raisin bran ( I add dried cranberry's / craisins for extra fiber and flavor ). Also when in desperation Milk of Magnesia is a life savor!!!!
I want to add that I am brand new to the Mayo connect boards so I am still learning.
